The actors of "Mean Girls," starring Lindsay Lohan, Rachel McAdams, Lacey Chabert and Amanda Seyfried, have started a GoFundMe campaign hoping to raise $300,000 for shooting victims. The cast is working with the National Compassion Fund, a program in the National Center for Victims of Crime, which also helped raise funds for victims of the Pulse nightclub shooting in Orlando, the Aurora movie theater shooting, and 9/11, according to the program's website.

The campaign had raised more than $21,000 in 19 hours, as of Tuesday afternoon. The first donation, in the amount of $1,003, was from Jonathan Bennett, who played Aaron, the love interest of Lindsay Lohan’s character.
